In Nautilus or Dolphin, you can see the trash by going to the location trash: where you can select and delete or restore files.
But if you want to remove them fast and from command line, the actual location is
where the organization of the local trash is like this:/home/droidzone/.local/share/Trash/
To clean up trash completely:sudo rm -r ~/.local/share/Trash/*
System trash on the other hand is at:/root/.local/share/Trash[/code]
which is exactly the same :)
